Cease to network

It’s easy to forget about networking when you’ve worked with one employer for a long time. But knowing who gets what done within a company isn’t enough.

"Failure to network can be detrimental when the time comes for an employee to find a new job," says Jennifer Brown, founder of PeopleTactics, a human resources firm.

"Employees need to ensure they continue to network throughout their careers so that they can stay in contact and connected with people who are able to help them, should they want or need to switch jobs."
